My Comcast cable box is connected via a 3' HDMI cable to one of the HDMI inputs on my XMC-1. Another 3'HDMI cable connects from the XMC-1 output to my Samsung 4K 9000 series TV. Every time I turn the system on the watch cable it's a complete crapshoot as to what will happen. I usually turn the XMC on first, then the TV (the satellite box stays on). On rare occasion, if I'm really lucky, the XMC sound and TV picture both come on and work normally! Unfortunately, what usually happens is one of the following:
1) The XMC starts outputting the cable sound but the TV screen is blank. After a few seconds it will display a message advising that it does not detect a signal on that input (which is of course the input that the XMC is connected to).
2) The sound and picture both come on but the sound cuts out for a nanosecond every 5 seconds or so.
3) There is no sound or picture whatsoever.
The remedies are as follows:
1) I turn the XMC and/or TV off and back on again. This almost never works, so I've pretty much quit trying it.
2) I remove the HDMI cable from the cable box and plug it in again. This restores both sound and picture about 50% of the time.
3) I turn the TV off and do a complete reboot of the XMC using the rear switch, then turn the XMC back on followed by the TV. This always works but needles to say is a 5+ min. pain in the a**
Every time I have to go through this, which is pretty much every evening, I "Rethink High End", although not in the way Emotiva would like me to.
I have spoken with Emotiva techs more times than I care to count. I appreciate their willingness to be has helpful as possible, but have never found a solution.
BTW: My BluRay also runs through the XMC and audio/video works as it should.
Any suggestions anyone??

Go to Comcast and swap out the box. If they’re anything like Optimum and the equipment belongs to them they will replace the box no questions asked.
Change that and also try another HDMI cable and recheck your RG hookup to the box.
Let comcast check you from their office and see how it goes,

Are you using a Fiber Optic HDMI cable?

No, regular HDMI. There's a fiber optic HDMI??

Couldn't hurt to swap the cable box but it feels to me more like a mis-communication between the box and the XMC-1. I've tried a couple of different HDMI cables. Currently using short Emotiva HDMI cables at their suggestion.

Currently using short Emotiva HDMI cables at their suggestion. Understood…..A fault in the box could be the root cause of the mis-communication. I would leave skid marks to get to Comcast. A pain but worthwhile. My local cable office SUCKS (Like going to the DMV.) While there, they tried to sucker punch me into an unnecessary tier level that gave me nothing but gave them an extra 16 a month. |

No, regular HDMI. There's a fiber optic HDMI?? Yes, I have a 10 Meter Ruipro Fiber Optic HDMI cable. It's not without issues though. After I connected one I had a problem. Depending on the system there can be HDCP (High-Bandwidth Digital Content Protection) issues whereby the "sink" (the tv) doesn't "see" a HDCP capable device, like my TiVo, and will stop communicating and lockup the XMC-2 after about 15 minutes of being in VRO, which then forces a cold boot of tv and XMC-2 to solve. It took me over a week of constant troubleshooting to find a really well disguised and hidden secret setting on my tv that allowed the tv to be happy and finally see my TiVo when my XMC-2 was in VRO. So if you get a fiber cable, just be prepared to go looking for a setting on your tv if you encounter an HDCP issue. It's not the fault of any processor, it's the display. |

I would ask for a new box. Assuming you have tried a different HDMI input on the XMC-1...just to rule out a bad HDMI input....

This problem is actually a very old one... The issue is brought about by the fact that cable boxes (actually, most STBs) never power off. They simply go into "standby" or "sleep" mode. While this idle state is necessary due to the fact that they must be "online" 24/7 to receive their guide updates, the problem presents itself when they don't kill their HDMI video output in the process. Some, or maybe most, will show a splash screen instead. But because your STB never powers off and allows the HDMI output to remain "alive", there's no HDMI renegotiation (handshaking) that's forced when you power your TV, AVR or processor back up. If HDCP has timed out (or locked out), you'll always end up exactly where you're at. Most often, switching inputs (and then back) forces a hot plug event. Sometimes, it doesn't (or it has no effect). Other times, you might be more successful switching to an inactive HDMI input before turning off the processor. However in severe cases, your only successful solution would be connecting the STB directly to the TV and using HDMI-ARC or Toslink to send audio back to your processor. In any case, I would agree with the other respondents above that there's absolutely no harm in requesting a new box from your service provider. And while doing so, I would adamantly request (a nicer way of saying "demand") a "new" box (not recycled) and one that is of their most recent generation. In the end, this might fix nothing, but you won't know unless you try...  |

You would think by now (and yes I have experienced this) the industry would have worked a fix into the technology to minimize the problem. That being said my Fire Stick (If I could make such a comparison) operates from that standpoint in very much, the same way the box does and yet I never have such an issue. I suppose part of the problem exists within what is actually being broadcast. |

Well, at least after 2 years I finally have a plausible explanation of what's going on- appreciate it. Think I'll get a new box from Comcast and if that doesn't work I'll hook the cable directly to the TV and back-load audio from the TV to the XMC.
Thanks-
